  • Patent number: 11810272
    Abstract: Methods for dehazing a digital image and for restoring an underwater digital image. The methods include the following steps: First, clustering pixels of a digital image into haze-lines, wherein each of the haze-lines is comprised of a sub-group of the pixels that are scattered non-locally over the digital image. Second, estimating, based on the haze-lines, a transmission map of the digital image, wherein the transmission map encodes scene depth information for each pixel of the digital image. Then, for a hazy image, calculating a dehazed digital image based on the transmission map.

  • Publication number: 20230112169
    Abstract: A method of estimating attenuation coefficient ratios from digital image acquired in a scattering medium is disclosed. The method may include, receiving a digital image acquired in a scattering medium; and estimating the attenuation coefficient ratios directly from the digital image. Further is disclosed a method of estimating veiling light values. The method may include receiving a digital image acquired in a scattering medium; and estimating the veiling light value directly from pixels in the digital image associated with objects.
